    Dictionary of American Naval Fighting Ships: The second Bonita, a wooden-hulled motor boat built by the Holmes Motor Co., of Mystic, Conn., was acquired by the Navy for use as a section patrol craft and delivered to the Navy by her owner, Mr. Robert Windsor of Boston, on 17 May 1917.

    While no deck logs for this boat seem to exist, other records indicate that she received the classification SP-540 and operated in Boston harbor as a patrol craft through the end of World War I. Not long after the war's end, on the night of 25 and 26 November, Bonita sank as the result of a collision with the fishing schooner Russell. Repeated efforts to locate Bonita's wreck proved unsuccessful, and her name was struck from the Navy List on 18 December 1918.
